Answer:
1. H = 29 cm
2. θ = 44°
Step-by-step explanation:
1. We can find the height of the triangle by considering the isosceles triangle as two right triangles. The height can be found by using Pitagoras:
Where:
L: is the sides of the isosceles triangle = 42 cm
B: is the base = 30 cm
H: is the height =?
Then, the height is:
2. The two equal angles (θ) can be found using the following trigonometric identity:
Hence, the two equal angles are 44°.
I hope it helps you!
You have to check f(1) in each one to see if it's right and for f(4)
the 24th term of the arithmetic is 146
Answer: x = - 1,36
Step-by-step explanation:
-1.78 – (-0.42) = x
-1.78 + 0.42 = x
- 1,36 = x
x = - 1,36

Step-by-step explanation:
I don’t really wanna help, so thanks for the points! Don’t scroll down! I’m warning you!!!
Figure 1 and Figure 4 have the same areas because the area of a parallelogram is just length times width.
Figure 1: 15×4=60 cm
Figure 2: 18×3=54 cm
Figure 3: 11×6=66 cm
Figure 4: 12×5=60 cm
As you can see, figure 1 and figure 4 have the same areas. So, C is the correct answer.
